T0. tillauhom it mayconceM-fl Befit known thatl, THOMAS F. CONNOR, a,citizen of the United States, residing at Decorah, in the county ofWinneshiek and Stateof Iowa, have invented certain new and usefulImprovements in Wrenches, of which the following is a description. 7 Myinventionbelongs to that general class ofdevices knownas wrenches andrelates particularly to a wrench which may be quickly'and easilyappliedor removed. The inventionhas among its objects the production ofa-device of ,th'ekind described that is simple, efiicient, durable andsatisfactory for use wherever ;found applicable. Many other Objects .andadvantages of, the construction hereinv shown and described will beobvious to. those skilled in the art from the disclosures herein given.f

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparicularly pointed out in the claim. 1.1;;

In the drawings, wherein like reference characters indicate like orcorresponding parts,

Figure 1 is a side elevation of one form of my wrench;

Fig. 2 is a sectional same;

Fig. 3 is a sectional view taken substantially on line 33 of Fig. 1;

Fig. 4 is a sectional view tially on line 44 of Fig. 1;

Fig. 5 is a sectional view similar to Fig. 3, showing the parts inchanged position;

Fig. 6 is a perspective view of the member 8;

Fig. 7 is a sectional View of a modified construction Fig. 8 is asectional view taken substantially on line 8-8 of Fig. 7;

Fig. 9 is a side elevation of another form of wrench;

Fig. 10 is a. sectional view taken substantially on line 1010 of Fig.19; and

Fig. 11 is a sectional view, taken substantially on line 1111 of Fig. 9.7

Referring to the drawings, Figs. 1 to 6 represent an ordinary wrench, inwhich 1 is a suitable shank provided with a head or engaging jaw 2, theshank being extended as at 3 the desired length to provide a handle. Thesame is also preferably threaded at one edge 4 to form a cog-rack, andmay be proview through the taken substan- Specification of Lettersfatent. Patented Sept, 20 1921. Application filed February s, 191 9.Serial in. 274,768.

vided With a stop pin 5 or equivalent, the purpose of which will behereafter referred to. Mounted on the shank 1 is a slidingly movablemember 6 having a cooperating jaw 7. Also arranged on the shank andmovable with the head 6, is what may be termed a nut or sleeve 8, whichis threaded as at 9 to engage with the threads 4. A groove or threadlesspart 10, however, is formed on the interior of the nut so that when thenut is turned substantially as shown in Fig. 5, the groove and cog-rackare brought into'registry, the part may readily slide along the shaft '3free from the restrictions of the nut. I have shown filler blocks 11,threaded to engage the interior thread 9, these maintaining the nut inplace and sliding freely when the nut is moving onthe shank. The nut orsleeve 8 is shown provided with a circumferential groove 12 which isarranged to be engaged by an engaging member 13- on the head 6, the samepermitting the rotation of the nut, but causing, the head to slide withthe nut when turned or moved on the shank. A stop pin 14 is also shownwhich will limit the movement of the nut so that the groove 10 may bebrought to register with the threads 4 when desired, so that theregistration may be brought about quickly and without inconvenience.

The construction shown in Fig. 7 is very similar, except that on theshank 21 having head 22 is arranged a head 16 provided with extendingportions 17. A block 18 is shown, and the parts secured together byrivets 18 or equivalent means. A jaw member 19 in this case is provided,the same being adjustably secured in place by a bolt, screw, rivet orthe equivalent 20, permitting the same to oscillate slightly. In thiscase the jaws are preferably formed with engaging teeth 7 or serrations26 and 27. A nut 28 similar blocks 34 corresponding to blocks 11 arealso.

provided.

A simplified construction of the wrench is shown in Figs. 9, 10 and 11,in which 39 represents a shank provided with a jaw 40, a movable member36having a jaw 44 to engage with the nut 38 which is internallythreaded, and provided with the groove 45. In this case the head 36 isextended as at 87 and provided withlthreads 46. When the nut is turnedand engages with the threads 42, the head36 is locked against movement.

WVith all of the constructionsillustrated and described, the headcarrying one of the movable jaws may be shifted on the shank to bringthe jaws the'desired distance apart, after which the nut 8, 28 or 38, asthe case maybe, is given a turn, locking the head against movement sothat the jaws will perform their function. The device is exceedinglysimple, consists of aminimum of parts, is extremely durable and will noteasily get out of order. The same may be manufactured at comparativelysmall cost. The saving in time in adjusting the head will amount toconsiderable, and is of no small importance at the present time wherethere is a shortage of labor and every possible minute should beutilized.

Having thus described'my invention, it

' is obvious that various immaterial modifications may be made in thesame without departing from the spirit of my invention; hence I do notwish to be understood as limiting myself to the exact form,construetion, arrangement and combination o1 scribing witnesses.

parts herein shown and described or uses mentioned.

What I claim is:

A device of the kind'described, comprising a substantially fiat shankhaving a cog aw, in combination with a part slidably mounted'u'pon saidshank and extended on one side thereof, said last mentioned part havingan open slot therein, an oscillat ing cooperating jaw mounted in saidslot in the extended portion of the sli'dable memher, a rotatablescrew-threaded nut to control the movement of the slidable member partadapted to be brought into registry with said cog racks,whereby'tlienut, filler blocks and slidable member may he slid on saidshank, and a stop limiting said sliding movement away from said fixedjaw.

In testimony whereof I have hereunto signed my name in the presence oftwo sub-i THOMAS memos."
